    • Influence of the position and size of various deterministic defects on the high cycle fatigue resistance of a 316L steel manufactured by laser powder bed fusion 
      Article dans une revue avec comité de lecture
      ANDREAU, Olivier; ccPESSARD, Etienne; ccKOUTIRI, Imade; PEYRE, Patrice; ccSAINTIER, Nicolas (Elsevier, 2021)
      Optimized 316L steel samples were manufactured using laser powder bed fusion and tested in high cycle fatigue at R = 0.1. They showed microstructural crack initiation and outstanding fatigue properties. Additional fatigue ...
    • Enhanced parametric shape descriptions in PGD-based space separated representations 
      Article dans une revue avec comité de lecture
      KAZEMZADEH-PARSI, Mohammad Javad; ccAMMAR, Amine; DUVAL, Jean-Louis; ccCHINESTA SORIA, Francisco (2021)
      Space separation within the Proper Generalized Decomposition—PGD—rationale allows solving high dimensional problems as a sequence of lower dimensional ones. In our former works, different geometrical transformations were ...
    • Sheet Molding Compound Automotive Component Reliability Using a Micromechanical Damage Approach 
      Article dans une revue avec comité de lecture
      LARIBI, M. A.; TIEBI, R.; TAMBOURA, S.; ccSHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph (Springer Verlag (Germany), 2020)
      The mastering of product reliability is essential for industrial competitiveness. If for metallic materials the topic is well-known, especially in automotive industry, Original Equipment Manufacturers are expecting strong ...
    • Fiber Orientation and Concentration in an Injection-Molded Ethylene-Propylene Copolymer Reinforced by Hemp 
      Article dans une revue avec comité de lecture
      DUPUIS, Antoine; PESCE, Jean-Jacques; FERREIRA, Paulo; ccREGNIER, Gilles (MDPI, 2020)
      This paper characterizes and analyzes the microstructures of injection-molded polypropylene parts reinforced with 20 wt% of hemp fibers in order to understand the process induced variations in thermomechanical properties. ...
    • Quantitative Structural Study of Cold-Crystallized PEKK 
      Article dans une revue avec comité de lecture
      TENCE-GIRAULT, Sylvie; QUIBEL, Jonathan; CHERRI, Alexis; BIZET, Stéphane; ILIOPOULOS, Ilias; ccFAYOLLE, Bruno; ccROLAND, Sébastien (American Chemical Society (ACS), 2021)
      Poly(ether ketone ketone) (PEKK) is a semicrystalline polymer investigated for highly demanding applications in aerospace, transportation, electronics, and oil & gas industries. The properties required for these applications, ...
    • Ageing of UHMWPE in presence of simulated synovial fluid 
      Article dans une revue avec comité de lecture
      VISCO, Annamaria; SCOLARO, Cristina; ccRICHAUD, Emmanuel (Elsevier BV, 2021)
      In this paper, the biomedical grade Ultra High Molecular Weight Polyethylene (UHMWPE) has been soaked at different temperatures in Simulated Synovial Fluid (SSF); diffusion coefficient, hardness, roughness and wettability ...
    • Multiscale study of poly(butylene terephthalate) hydrolysis 
      Article dans une revue avec comité de lecture
      LOYER, C.; DUVAL, V.; ccREGNIER, Gilles; ccRICHAUD, Emmanuel (Elsevier BV, 2021)
      This paper reports the hydrolysis of several PBT materials (pigmented or not). Degradation was monitored by gel permeation chromatography (chain scission), DSC (crystalline morphology), tensile test (residual mechanical ...
